Description
1 2328133 WATER TREATMENT APPARATUS USING PLASMA REACTOR AND METHOD
THEREOF
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a water treatment apparatus using a plasma reactor and a method thereof, and in particular to an improved water treatment apparatus using a plasma reactor and a method thereof which are capable of efficiently removing non-biodegradable pollutants contained in a polluted water using a plasma formed by applying a high voltage of 30KV 150KV to a plasma reactor.
is 2. Description of the Conventional Art
Recently, much attention has been paid to preventing a fresh air and clean water from being polluted.
The preventing technique of environmental pollution is generally classified into an air pollution prevention technical field, a water pollution prevention technical field, an industrial waste disposal technical field, and a pollution-free technical field. Among the abovedescribed technical fields, the water pollution prevention technique will be explained.
In the water pollution prevention technique, much study has been performed in order to provide an waste water treatment system.
However, any efficient and economical technique has not been disclosed for supplying a clean water. Namely, so far in the industry for treating the polluted water, an organic material (such as a carbon hydrogen) contained in the polluted water is 2 simply treated to be removed from the polluted water so that a BOD (Biochemical Oxygen Demand) is lowered for thereby completing a water treatment process, and then the water having lowered BOD is flown to river, lake or the like.
Namely, as the industry is advanced and people are rushed to city, a various kinds of polluted materials which were not generated in the past are increasingly generated. So far, the thusly generated polluted materials have been treated without accurately analyzing any toxic components contained in the polluted materials and any effects thereof to the environment.
For example, chlorine which is generally used for disinfecting bacteria contained in water is known to form THM (Tri-Hak-Methane) which may cause cancer.
In addition, the polluted water containing much nitrogen and phosphorus is increasingly generated from home and transferred into river, lake, or the like for thereby increasing BOD therein.
As shown in Figure 1, in the conventional water treatment method, polluted water passes through a first stabilization tank and then flows to a concentrator.
The polluted water transferred from the concentrator is separated into a solid sludge and a polluted water.
The solid sludge contained in the polluted water is transferred to a post incinerating apparatus through a drying apparatus and an incinerator.
The polluted water transferred into an air stripper passes through a second stabilizationú The sludge gathered on the bottom of the second stabilization tank is transferred to the sludge gathering apparatus.
The sludge gathered by the sludge gathering apparatus is transferred to the drying apparatus.
(=&nk In addition, the polluted water passed through the second stabilization4is transferred to a aeration tank for thereby separating the polluted water into a sludge and a polluted water, and then the polluted water is transferred to a RTO (Regenerative Thermal Oxidizer).
At this time, a part of the sludge transferred into the active sludge reactor is transferred into the sludge gathering apparatus, and another part of the same is transferred into a regenerative thermal oxidizer together with the polluted water passed through the aeration tank, and another part of the same is flown to the outside as a waste water.
However, the above-described polluted water treatment apparatus is unable to effectively remove nitrogen, phosphorus, or toxic materials contained in the polluted water.
In particular, the polluted materials generated from factories and containing L - a cho[ine component, namely, PCE (perch loroethylene), PC13s (polychlorinated is biphenyl), and DCP (dichlorophenol) may contain a very toxic material. Furthermore, the above-described polluted material generates a secondary toxic material in reaction with a clolne component contained therein. Therefore, when the polluted water containing the above-described polluted material is flown into river or lake, the river or lake are seriously damaged compared to other polluted water which does not contain the above-described polluted materials.
In addition, the chlorine-contained polluted material is not easily dissolved under the natural environment nor naturally dissolved into water. There is not a proper method for economically eliminating the above-described pollutants.
For example, in the case of the dyeing component polluted water, the dyeing component polluted water contains cho ne components as well as nitric acid L- 4 components, so that it is very harmful and has a very high toxicity. The abovedescribed pollutants are controlled as one of the most toxic materials in most countries.
For reference, the dyeing factory occupies about 6% for the factories which generate pollutants and about 3.5% of the total amount of pollutants. At a glance, such figures seem to cause less pollution problems compared to other pollutants but the pollution degree (treatment-before BOD) is about 24% of the total degree. Therefore, the dyeing component polluted water causes much pollution problem.
For effectively treating the above-described polluted water, there are known a physical and chemical treating method, a biochemical treating ffieffibe, a coagulation and sediment method, Fenton oxidizing method, an electron beam processing method, an activated charcoal adsorption method, a film separation method, and a plasma processing method.
Among the above-described methods, the physical and chemical processing is method is directed to preprocessing the pollutant before a polluted water is treated.
Therefore, the physical and chemical processing method is incapable of actually eliminating pollutants.
In addition, as the biochemical processing method an activated sludge process is widely used in the industry for adsorbing and dissolving organic materials using activated aerobic bacteria. In this method, a lot of sludge is generated, and in particular the dyeing material contained in the dyeing component polluted water is not degraded. Even though it is degraded, it may generate a secondary toxic material, so that the pollutant treating efficiency is very low. In order to overcome the above-described problems, a method which uses an anaerobic bacteria among the biochemical processing method is disclosed. However, this method has a problem in that it takes a long time (tens of days) for processing the non- biodegradable pollutants.
The coagulation and sediment method is capable of eliminating wide range of pollutants but is incapable of eliminating a dissolvable material such as a soluble component.
Fenton oxidizing method (disclosed by Fenton of England in the end of 19th century) is a method for processing polluted water using a phenomenon that strong oxidization occurs when H202 and Fe ions react. This method has a disadvantage in that agent provided for strong oxidization is very expensive.
Ozone processing method is implemented using ozone having strong oxidizing force. This method is good for dissolving a non-soluble material, deodorizing a predetermined smell, and eliminating coloring components. However, the ozone generator is expensive, and an ozone occurrence efficiency is no more than 5%, so that power consumption is increased.
is The electron beam method has an advantage in that it is possible to overcome the problems encountered in the above-described methods. However, a system for generating electron beams and implementing acceleration for the beams is complicated and expensive, so that the operation cost of the system is increased like the ozone processing method. In addition, the depth of water into which electron beams pass through is a few of mm, the polluted water should be fast flown over the region which is wide and shallow for thereby implementing a water treatment process. In addition, the electron beam generator is bulky and is designed to generate a high capacity for thereby increasing a fabrication cost. Furthermore, the electron beam generator may generate harmful X-ray.
The activated charcoal adsorption method is directed to adsorbing pollutants using an activated charcoal having a plurality of fine holes. In this case, the activated charcoal is recyclable. However, the processing efficiency of the pollutants is decreased, so that it is not used solely.
The film separation method has an advantage in that a film material is separable based on its particle size and chemical affinity by a physical and chemical function of the film materZal. However, the fabrication cost is increased, and a preprocessing procedure is complicated. In particular, if the preprocessing procedure is not properly performed, the expensive facility may be damaged.
In the method for generating an activated radical based on a plasma for thereby implementing a water treatment, there are the following problems. First, a relatively high electric field (over 2xl 0' 3xl 05 V01t1CM) is needed for obtaining an electrical insulation destruction under water. Second, since a steamer is fast transferred by a discharging operation under water, the streamer corona is not continuously implemented, so that an arc or spark easily occurs. Third, even though is the streamer corona continuously occurs, since the reactive region of the activated radical generated by the streamer is narrow, it is impossible to effectively eliminate the pollutants. The above-described problem may be overcome by the electron beam method which uses MeV (Mega electron Volts). However, the electron beam method is implemented by a relatively bulky system, and the human body may be hurted.
SUMMARY OF THE INVENTION

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The water treatment apparatus using a plasma reactor and a method thereof according to the present invention will be explained with reference to the accompanying drawings.
As shown in Figure 2, in a plasma reactor 1, a polluted water inlet 3 is formed at a lower portion of a housing 2, a polluted water outlet 4 is formed at an upper portion of the housing 2. A plurality of beads 5 are filled in the interior of the housing 2.
At this time, the size and number of the beads 5 filled in the interior of the housing 2 are determined by the density and processing amount of the pollutants.
For example, if the density of the pollutants contained in the polluted water is high, or if the processing amount of the same is large, the beads 5 of small diameter are filled in the interior of the housing 2. On the contrary, if the density of the pollutants contained in the polluted water is low, or the processing amount of the pollutants is small, the beads 5 of large diameter are filled in the interior of the housing 2. The size of the beads filled in the interior of the housing 2 is in a range from a few of mm to a tens of mm based on the application of the same. In addition, the number of the beads is determined by the application thereof.
At this time, the beads 5 filled in the interior of the housing 2 are made of acryl, a ferro dielectric such as BaTi03, a hollow metallic member, a polyethylene, nylon, a glass without Pb, a ceramic of alumina group, a photocatalyst such as Ti02, a polyethyiene coated with nickel, etc. and the beads 5 are a hollow ball shape, a cylindrical shape, etc.
In. addition, the lower surface of the lowermost beads 5 filled in the housing 2 and the upper surface of the uppermost beads 5 contact with predetermined shaped electrodes 6, respectively, and a pulse generator 7 is installed in the housing 2 for generating the pulses of a few of micro or nano seconds unit using a high voltage of 30KV 150KV and transmitting the thusly generated pulses to the is electrodes 6.
The pulse generator 7 and the electrodes 6 are connected by a power cable 8, Here, the electrodes 6 are formed of a wire-plate type, a wire-wire type, or a cylinder-wire type.
In detail, one electrode is formed of a wire, and the other electrode is formed of a plate. In addition, both electrodes are formed of a wire. In another embodiment, one electrode may be formed of a cylinder, and the other electrode may be formed of a wire.
The electrode 6 made of a wire is formed in order for the electrode 6 not to face the flowing of the polluted water with its flat surface so that the unpolluted water is not blocked by the electrode 6 when it passes through the interior of the housing 2.
In addition, an air inlet hole 9 is formed on the lower surface of the housing 2, and an air outlet hole 10 is formed on the upper surface of the same. The air inlet hole 9 is connected with a compressed air generation member such as an air compressor 11, so that air bubbles are flown into the interior of the housing 2 during the processing operation of the polluted water for the purpose that the air bubbles flow between the beads 5 for thereby generating smaller air bubbles, whereby the pollutants contained in the unpolluted water are separated, and oxygen is effectively supplied thereinto so that ozone is more easily generated by the plasma. In addition, the plasma is effectively transferred between the beads when applying voltage to the electrode.
A regulator 13 is installed in an air supply tube 12 connecting the air compressor 11 and the housing 2 for controlling the amount of the compressed air supplied into the interior of the housing 2.
The polluted water treatment apparatus using a plasma reactor according to the present invention will be explained.
As shown in Figures 2 and 3A, the polluted water treatment apparatus using a plasma reactor according to the present invention includes a polluted water gathering tank 14 for gathering polluted water, more than one plasma reactor 1 for treating pollutants contained in the polluted water formed in the shape of a water film 25 on the outer circumferential surface of each of the beads 5 using the plasma when the polluted water is flown into the housing 2 through a first connection tube 15 connected with the polluted gathering tank 14, a pulse generator 7 for supplying pulses so that the plasma is generated in the interior of the plasma reactor 1, a storing tank 17 for storing the polluted water when the polluted water which is first treated by the plasma reactor 1 is flown thereinto through the second connection tube 16, a pollution measuring apparatus 26 for measuring the pollution degree of the polluted water stored in the storing tank 17, and a return tube 21 for transferring the polluted water stored in the storing tank 17 to the polluted water gathering tank 14.
A pump 22 is installed at a predetermined portion of the return tube 21 connecting the polluted water gathering tank 14 and the storing tank 17 for generating a predetermined pumping force so that a part of the polluted water which is first treated and stored in the storing tank 17 is caused to be flown again into the polluted water gathering tank 14. The pollution degree of the polluted water which is first treated by the plasma reactor 1 is measured by the pollution degree measuring apparatus 26 in the storing tank 17. As a result of the measurement, if the pollution degree exceeds a predetermined degree, the polluted water is retreated by the plasma reactor 1 by flowing the polluted water to the polluted water gathering tank 14.
In addition, in the present invention, a plurality of plasma reactors may be installed for effectively treating the pollutants contained in the polluted water using plasma. In this case, the plurality of the plasma reactors are preferably connected in series or in parallel or in combination with the serial and parallel connections.
As shown in Figure 3A, first and second plasma reactors la and 1b are connected in series by a third connection tube 18. The second connection tube 16 connecting the second plasma reactor 1b and the storing tank 17 is connected with a bypass tube 19 connected with the first plasma reactor 1 a. At this time, valves 20a and 20b are installed in the third connection tube 18 and the bypass tube 19, respectively.
Therefore, when the pollutants are treated using the first plasma reactor la and discharge to the storing tank 17, the valve 20a installed in the third connection tube 18 is closed, and the valve 20b installed in the bypass tube 19 is opened.
When treating the pollutants using two plasma reactors 1, the valve 20a installed in the third connection tube 18 is opened, and the valve 20b installed in the bypass tube 19 is closed.
In addition, as shown in Figure 3B, in the second embodiment of the present invention, a bio-reactor 23 is connected with the storing tank 17 by a fourth connection tube 24 for decreasing the operational cost and selectively treating the pollutants based on the type of the pollutants contained in the polluted water.
The bio-reactor 23 is a fluidized bed type or a fixed bed type. In this structure, em bacteria remains, floated state in the bio-reactor 23 or may be attached to the inner surface of the same based on the type of the pollutants to be treated. A bubbling is means is installed in the bio-reactor 23 for increasing a treating efficiency of the pollutants.
Generally, as a bubbling means, an air compressor may be used for generating a compressed air, or an impeller is used for generating a predetermined water flowing.
In another embodiment of the present invention, the air compressor 11 generating a compressed air into the interior of the plasma reactor 1 is connected with the bio-reactor 23 by an air supply tube 12 for thereby also forming a bubbling means.
Figure 4 is a block diagram illustrating the procedure for treating the polluted water using a plasma reactor according to the present invention.
14 - The polluted water treatment method according to the present invention is classified into a first process which is implemented by the plasma reactor 1 and a second process which is implemented by the bio-reactor 23.
Therefore, in the present invention, the reactors 1 and 23 may be independently operated. The processing procedure of the polluted water will be explained in detail.
First, it is judged that whether the plasma reactors 1 for implementing the first treating process are connected in series or in parallel, and it is judged whether the bio-reactor 23 is used for implementing the second treating process.
If the polluted water to be processed is a high density, a plurality of the plasma reactors 1 are connected in series for thereby maximizing the polluted water processing time, and if the polluted water is a relatively low density, the plasma reactors 1 are connected in parallel for thereby increasing the processing capacity of the polluted water per hour.
In order to effectively eliminating non-soluble materials such as PC13s, PCE, DCP, etc. in which chlorine component is contained, the pollutants, namely, the non dissolvable material which is formed when one chlorine group is detached by the plasma in the plasma reactor 1, are dissolved by bacteria, and the bio reactor 23 is further used.
The operation of the polluted water treatment apparatus using the plasma reactor according to the present invention will be explained with reference to the accompanying drawings.
In a state that the operational system of the facility is set according to the type and amount of the pollutant water, the polluted water generated due to industrial activity is gathered Cw introduced into the polluted water gathering tank 14, and the - thusly gathered polluted water is flown into the plasma reactor 1 through the first connection tube 15.
When the pollutant water is flown into the interior of the plasma reactor 1, as shown in figure 2, a water film 25 is formed on an outer circumferential surface of each of the beads 5 filled in the housing 2.
At this time, when the compressed air generated by the air compressor 11 is controlled by the regulator 13 and is introduced into the interior of the housing 2, a plurality of air bubbles pass through the spaces formed between the beads 5, and then the air bubbles are split for thereby dividing the pollutants, so that oxygen easily becomes ozone state by the plasma.
In this state, when a predetermined pulse is applied to the electrodes 6 contacting with the beads 5 filled in the uppermost portion of the housing 2 and the beads 5 in the lowermost portion of the housing 2, a plasma is generated in the housing 2, so that the polluted water which are formed on the outer circumferential is surfaces of the beads 5 in a film state are treated by the plasma.
At this time, the characteristic of the pulse which is transferred from the pulse generator 7 for thereby generating plasma affects the polluted water treatment capacity of the plasma reactor 1.
In the second embodiment of the present invention, the problems encountered in the conventional art are overcome by applying a high voltage of 30KV - 150KV and the following principle without generating harmful X-ray.
Con L- Generally, water has a relatively high dielectric (e=81) compared to air (E=1).
CO 91 Ahallt CD #X."
The dielectric,?f water is similar with the dielectrickof the ceramic.
Therefore, in order to implement the plasma reactor 1 as shown in Figure 2, when the water films 25 are formed on the outer circumferential surfaces of the is beads 5 by flowing the polluted water from the polluted water gathering tank 14 into the housing 2 through the polluted water inlet 3, the pulses generated by the pulse generator 7 are supplied to the electrode 6 for thereby forming plasma, so that the pollutants contained in the polluted water are destructed.
Namely, the distance between the beads 5 is the same as the thickness of the water film 25. The thickness of the water film 25 is a few hundreds of S. bhqt- micrometer, it is possible to effectively destruct the pollutants contained in the L polluted water using the plasma generated in the housing 2.
In more detail, a voltage of 20-150KV is applied to the water film having the above-described thickness, a relatively high electric magnetic field is formed.
Therefore, plasmas are formed between the beads 5 in a shape of web. The activated radicals such as 0, H, 03, H2021 UV, e -aq are generated in the housing 2 by the thusly generated plasmas. The thusly generated activated radicals are reacted with the pollutants contained in the polluted water.
In particular, since an oxygen atom has a very strong oxidization force compared to the oxygen molecular, it is possible to effectively oxidize almost L_pollutants.
In addition, since it is possible to generate the activated radick on the spot, the system is operated very economically.
The hydrogen (H) and OH group generated by the plasma generated in the housing 2 reduce the nitrogen (N) and phosphorus (P) contained in the polluted water, so that it is possible to easily remove the nitrogen (N) and phosphorus (P).
Even though the oxygen atom and UV are generated for generating ozone using the conventional ozone generator, in this case, the life span of the oxygen atom is a few seconds. Therefore, only the ozone having a life span of 10 through i 17 - minutes is used, and other activated radicle including the oxygen atom are eliminated, so that it is not applicable for the pollutant water processing apparatus.
The pollutants contained in the polluted water are first eliminated by the plasma reactor 1. The thusly processed polluted water is flown into the next storing tank 17. The degree of the pollutants is measured. Thepolluted water is fully processed and is discharged to river or stream.
However, as a result of the measurement, 1 the density of the pollutants thecontained in the polluted water in the storing tank 17 exceeds 9 predetermined level, Rob the polluted water which is first processed by the plasma reactor 1 isdischarged to vJ h, ^J-- the outside. The(# " processed polluted waterstored in the storing tank 17 is h f arQcl tiú ZZ Z'.' A' of- Z 1 trans erred to the polluted water gathering tank 14:FheFea#,@-p. the above-described r,e-eeabp-ú(d carf.QA- e,,,b processes are, pfeeeseed- until the pollutants are fully eliminated.
So far, the operation that the polluted water containing organic materials which are not easily dissolved is flown into the plasma reactor for thereby effectively processing the polluted water was explained. In this case, when processing the pollutants using only the plasma reactor, the consumption of the electric power is increased based on the plasma reactor for thereby increasing the operational cost of the system.
Namely, in order to eliminate the pollutants contained in the polluted water 100% using only the plasma reactor, since a plurality of plasma reactors are connected in series, the consumption of the electric power is increased.
Figure 5 is a graph illustrating an experimental result which is obtained using only a plasma reactor for a water treatment method by eliminating DCP according to the present invention. As shown therein, in order to eliminate more than 60% of the pollutants contained in the polluted water, seven plasma reactors are connected is in series or the plasma process is performed seven time using one plasma reactor for thereby eliminating 60% of the pollutants.
In the case that there are provided pollutants which are easily processed, since it is possible to eliminate the pollutants 100% one time process using only the plasma reactor, the number of the plasma reactors is determined based on the type of the pollutants contained in the polluted water.
Since the polluted water generated by a factory contains pollutants which are not easily processed, the process should be performed several times for thereby increasing the operational cost of the system. Therefore, preferably, the plasma reactor and the bio-reactor are connected in series for thereby effectively processing the pollutants.
In the embodiment of Figure 3B, since the bio reactor which is capable of decreasing the operation time and cost is used, it is possible to decrease the operation and maintenance costs.
For example, if the polluted water contains non-soluble components such as PC13s, PCE, DCP, etc. including chlorine components, since the abovedescribed components are very stable, it is impossible to dissolve the above-described components using any type of bacteria. Therefore, it is needed to separate one chlorine group using a plasma with respect to a material having a plurality of chlorine 20 group. so that it is possible to easily process the pollutants using the bio-reactor 23.
Figure 6 is a graph illustrating a result which is obtained by processing the DCP by P.Putodu F1 Bacteria, in which DCP a chloro group is eliminated after eliminating one chforo group of the DCP in the plasma reactor during a water treatment. As shown therein, one chlorine group is separated from the material having a plurality of chlorine groups of the non-soluble pollutants contained in the - 19 polluted water and then the pollutants are transferred to the bio-reactor 23, so that the bacteria in the bio-reactor 23 process the non-soluble material 100% for 48 hours, from which one chlorine group is separated.
Therefore, the process is performed based on the following some cases. The first case is that it is impossible to process when the plasma process is not performed. The second case is that the electric power consumption is increased when the process is performed by only the plasma. As shown in Figure 7, the abovedescribed two cases may be combined for thereby effectively processing the pollutants.
Namely, the above-described two problems that the electric power consumption is increased based on the operation of the plasma reactor and the nondissolvable pollutants are not easily processed using the bioreactor are easily overcome by concurrently using the plasma reactor and the bio-reactor.
In addition, in the present invention, the piped water may be processed by using the plasma reactor.
Namely, when pulses are supplied to the electrodes 6 in the housing 2, a web-like plasma having more than about 1 OeV is generated. At this time, since the energy of leV corresponds to the temperature of about 110,0000C in theory the plasma generated in the housing 2 has more than about 100, 000'C.
Since the mass of the electron is relatively too small, it is impossible to actually feel the above-described temperature. Water is partially heated by a stream passing through the water, and then the water is quickly and finely expanded, so that shock wave is generated over the entire portions of the water molecular, whereby the shock wave destructs the bacteria contained in the polluted water.
In addition, the bacteria may be destructed by ozone generated when forming plasma.
When processing the piped water, since a lot of water should be processed per hour, a plurality of plasma reactors are preferably connected in parallel.
Therefore, the present invention may be adapted for processing the piped water and fabricating a heavy water.
Gt-rp- As described above, the pollutants contained in the polluted water La first processed by forming a plasma in the housing of the plasma reactor, and then L secondarily processed by the bio-reactor, so that the maintenance and operation costs are decreased.
In addition, it is easy to design the capacity of the system based on the pollution level of the pollutants and the processing amount, so that an effective pollutant processing is implemented.
